title: Pentoxifylline, ciprofloxacin and prednisone failed to prevent transplant-related toxicities in bone marrow transplant recipients and were associated with an increased incidence of infectious complications.
abstract: TNF-alpha (Tumor necrosis factor-alpha) is involved in many immunological and inflammatory processes, and might be expected to play an important role in the development of BMT-related complications. Triple therapy (pentoxifylline, ciprofloxacin and prednisone) with known anti-TNF activity was tested in 37 patients undergoing a hematopoietic progenitor transplant (HPT). A control group of 16 patients with similar characteristics was selected among consecutive patients receiving a HTP in a neighboring center who did not receive anti-TNF prophylaxis. Major transplant-related complications were registered (VOD, acute GVHD, infectious episodes, renal failure and mucositis) and survival status. TNF plasma concentrations were determined by ELISA, and pentoxifylline plasma concentrations were determined by HPLC. Among patients treated with pentoxifylline (PTX), ciprofloxacin and steroids, no difference in the mean survival time was observed compared with the control group. The incidence of procedure-related death up to day +35 was 11% in the study group and 6% in the control group. In spite of a tendency to a lower incidence of mucositis there was a higher incidence of infections (positive blood cultures) in the study group (49%) than in the control group (16.7%) (P = 0.16). This difference achieved statistical significance in patients receiving an allogeneic HPT (P = 0.05). It is likely that the use of steroids in the early period after transplant increases infectious episodes and makes control of GVHD difficult. The combined administration of steroids with pentoxifylline and ciprofloxacin has not proved beneficial in preventing mucositis, renal failure, VOD or GVHD, or in improving patient survival.
